You're forgetting that people want to be in an exclusive club, and if masterclass is able to really get 'masters' instead of jokesters, then being selected is worth the ego trip; plus if you get 30% of revenue, and you feel like you're god's gift, then you assume that number will be super duper high as well.

Personally I just love their name. Brilliant marketing. I'm starting to see it used outside of their product.
